Receiver, Method for Detecting an Error in a Signal Comprising a Datum, Method for Transmitting a Datum and a Method for Detecting an Error in a Signal

1. A receiver, comprising: a receiver circuit to receive a pulse width encoded signal having a first transition in a first direction, a second transition after the first transition in a second direction, a third transition after the second transition in the first direction and a fourth transition in the second direction of the signal, wherein the receiver circuit is adapted to determine a first time period between the first and third transitions and to determine a second time period between the second and fourth transitions, and wherein the receiver circuit is adapted to determine a datum based on at least one of the first time period and the second time period; and wherein the receiver is adapted to indicate an error, if the determined first and second time periods do not fulfill a predetermined verification relationship with respect to one another.

2. The receiver according to claim 1 , wherein the receiver is adapted such that the predetermined verification relationship is fulfilled, when a ratio of the determined first time period with respect to the determined second time period assumes a predetermined ratio value or falls within a predetermined range of ratios.

3. The receiver according to claim 1 , wherein the receiver is adapted such that the predetermined verification relationship is fulfilled, when the first and second time periods are essentially equal.

4. The receiver according to claim 1 , wherein the receiver circuit is adapted to determine the first time period based on the first and third transitions as transitions from a common predefined first signal level to a common predefined second signal level.

5. The receiver according to claim 1 , wherein the receiver circuit is adapted to determine the second time period based on the second and fourth transitions as transitions from a common predefined second signal level to a common predefined first signal level.

6. The receiver according to claim 1 , wherein the receiver circuit is adapted to determine the datum by processing the at least one respective time period, which is variable and depending on the datum.

7. The receiver according to claim 1 , wherein the receiver is adapted to not indicate an error, if the first and second time periods fulfill the predetermined verification relationship.

8. The receiver according to claim 1 , wherein the receiver circuit is adapted to determine a time basis for determining at least one of the first and second time periods based on a synchronization frame received before receiving the first, second, third and fourth transitions.

9. A method for detecting an error in a signal comprising a datum, the method comprising: receiving a first transition in a first direction, a second transition after the first transition in a second direction, a third transition after the second transition in the first direction and a fourth transition in the second direction of the signal; determining a first time period between the first and third transitions; determining a second time period between the second and fourth transitions; determining the datum to be received based on at least one of the first time period and the second time period; and indicating an error, if the determined first and second time periods do not fulfill a predetermined verification relationship with respect to one another.

10. A non-transitory computer readable medium having a computer program having a program code for performing the method of claim 9 , when the computer program is executed on a computer, a processor or another programmable hardware.
